Hi all! I am new to the community but I'm glad I found it because I have read so many great pieces of advice so far!
So my 1and half year old cat ( boy, neutered ) had two episodes of suspected feline lower track infection within a month. During the first one, I have noticed that he couldn't go to his litter and when he went , I saw some blood in his urine. We went straight to his vet and they gave us a course of Metacam for 5 days and a urinary supplement ( which I've been giving him every day since ). So this happened when we came back from a 5 day holiday but my trusted friend , who was coming to feed and pet him, did not observe abnormal behaviour while he was here and he would go to his litter normally. Second time, it happened a few hours after my partner left for a business trip , even though my cat was showing normal behaviour the day before. Again , we went to the vet and now he is on Metacam for 3 days. They ask me to provide an urine sample, which I did and turns out that he doesn't have any stones but they want another sample within 10 days to make absolutely sure that his kidneys are functioning ok. She said that everything seems to come down to separation anxiety. I have bought extra toys and pheromones diffusers and switched him to a urinary care diet ( hills ) because he has a tendency to eat more dry food and not drink water. Also , I bought him wet urinary care food and I add an extra teaspoon of water in there to make sure he is adequately hydrated. Is this something common of separation anxiety in cats?
